+## How to contribute to CoffeeScript
+
+* Before you open a ticket or send a pull request, [search](https://github.com/jashkenas/coffee-script/issues) for previous discussions about the same feature or issue. Add to the earlier ticket if you find one.
+
+* Before sending a pull request for a feature, be sure to have [tests](https://github.com/jashkenas/coffee-script/tree/master/test).
+
+* Use the same coding style as the rest of the [codebase](https://github.com/jashkenas/coffee-script/tree/master/src). If you're just getting started with CoffeeScript, there's a nice [style guide](https://github.com/polarmobile/coffeescript-style-guide).
+
+* In your pull request, do not add documentation to `index.html` or re-build the minified `coffee-script.js` file. We'll do those things before cutting a new release.

-<p>In order to accomplish this, move outdents that follow closing parens
-inwards, safely. The steps to accomplish this are:</p>
-
-<ol>
-<li>Check that all paired tokens are balanced and in order.</li>
-<li>Rewrite the stream with a stack: if you see an <code>EXPRESSION_START</code>, add it
-to the stack. If you see an <code>EXPRESSION_END</code>, pop the stack and replace
-it with the inverse of what we've just popped.</li>
-<li>Keep track of "debt" for tokens that we manufacture, to make sure we end
-up balanced in the end.</li>
-<li>Be careful not to alter array or parentheses delimiters with overzealous
-rewriting.</li>

+      Besides being used as an ordinary programming language, CoffeeScript may
+      also be written in "literate" mode. If you name your file with a
+      <tt>.litcoffee</tt> extension, you can write it as a Markdown document &mdash;
+      a document that also happens to be executable CoffeeScript code. The compiler
+      will treat any indented blocks (Markdown's way of indicating source code)
+      as code, and ignore the rest as comments.
+    </p>
+
+    <p>
+      Just for kicks, a little bit of the compiler is currently implemented in this fashion:
+      See it

+    </p>
+

+      Source Maps
+    </h2>
+
+    <p>
+      CoffeeScript 1.6.1 and above include support for generating source maps,
+      a way to tell your JavaScript engine what part of your CoffeeScript
+      program matches up with the code being evaluated. Browsers that support it
+      can automatically use source maps to show your original source code
+      in the debugger. To generate source maps alongside your JavaScript files,
+      pass the <tt>--map</tt> or <tt>-m</tt> flag to the compiler.
+    </p>
+
+    <p>
+      For a full introduction to source maps, how they work, and how to hook
+      them up in your browser, read the
